wheel  nuts can  cause  the wheel  to become  loose 
and  even  come 
off. This  could  lead  to an  accident. 
Be  sure  to  use  the correct  wheel  nuts. 
If you  have 
to  replace  them,  be  sure to get  new 
GM original 
equipment  wheel  nuts. 
NOTICE: 
Improperly  tightened  wheel  nuts can lead to 
brake  pulsation  and  rotor  damage. To avoid 
expensive  brake repairs,  evenly tighten the  wheel 
nuts  in  the proper  sequence and  to the proper 
torque  specification.  Used  Replacement  Wheels 
Putting  a  used  wheel 
on your  vehicle  is 
dangerous. 
You can’t  know  how  it’s  been  used  or 
how  far it’s  been  driven.  It could  fail  suddenly 
and  cause  an accident. 
If you have  to  replace  a 
wheel,  use 
a new GM original  equipment  wheel. 
Using the Wheel Lock Key 
The  wheel  lock  key  sits in a small depression in 
the 
trunk rail directly under the left-hand rear 
compartment  cover. 
Your vehicle’s wheel lock  key has a unique registration 
number.  The registration number is printed  on a card 
included  in  your lock nut package. 
Also, on this  card, is 
lost  key replacement information. This number is  not 
recorded  by 
GM or your dealer, so be sure  not to lose 
this  card. 
You will need the information  if  you ever lose 
your  wheel  lock key.   

Downloaded from www.Manualslib.com manuals search engine If you or someone  else is going to remove the wheels  on 
your  vehicle,  make  sure  that the special wheel nut socket 
and  wheel  lock key 
are being used. 
NOTICE: 
Your  wheels  could  be  damaged if the wheel  nut 
socket 
is not  used  to  remove  your  vehicle’s  wheels. 
The  wheel  nut  socket  can  be used  with an air wrench or 
a  torque  wrench.  The wheel  lock key can be  used  with  a 
torque  wrench,  but  not  with  an  air or impact wrench. 
I NOTICE: 
Your  wheel  lock  key or lock  nuts  could  be 
damaged  if an 
air or  impact  wrench is used  with 
this  key. 
Tire Chains 
NOTICE: 
Don’t  use  tire chains.  They  can  damage your 
vehicle  because  there’s  not  enough  clearance. 
Use  another  type of traction  device  only 
if its 
manufacturer  recommends it  for use  on  your 
vehicle  and  tire  size  combination  and  road 
conditions.  Follow  that manufacturer’s 
instructions. 
To help  avoid  damage  to your 
vehicle,  drive slowly,  readjust  or  remove the 
device 
if it’s  contacting  your  vehicle,  and don’t 
spin your  wheels. 
If you do  find  traction  devices that will fit, install 
them  on  the rear  tires.
